Merge pull request atomvm#1024 from fadushin/release-hello_world

Add hello_world AVM to release (for testing Homebrew Formula)

This PR adds the `hello_world` AVM file to the release. This is useful for
producing a releasable Homebrew Formula, as the Homebrew team requires at least
one meaningful test in order to commit to their repository.
